Microtopography-Dominated Discontinuous Overland Flow Modeling And Hydrologic Connectivity Analysis, Jun Yang Jan 2014

Microtopography-Dominated Discontinuous Overland Flow Modeling And Hydrologic Connectivity Analysis, Jun Yang

Civil and Environmental Engineering

Surface microtopography affects a series of complex and dynamic hydrologic and environmental processes that are associated with both surface and subsurface systems, such as overland flow generation, infiltration, soil erosion, and sediment transport. Due to the influence of surface depressions, overland flow essentially features a series of progressive puddle-to-puddle (P2P) filling, spilling, merging, and splitting processes; and hydrologic systems often exhibit threshold behaviors in hydrologic connectivity and the associated overland flow generation process. It is inherently difficult to realistically simulate the discontinuous overland flow on irregular topographic surfaces and quantify the spatio-temporal variations in dynamic behaviors of topography-dominated hydrologic systems. …

Synthesis And Characterization Of 2,3-Difunctionalized Thieno[3,4-B]Pyrazine-Based Terthienyls Structure-Function Relationships And Side Chain Tunability, Ryan Schwiderski

Chemistry and Biochemistry

The ability to tune the physical, electronic, and optical properties of polymer precursors has garnered a great deal of interest in the conjugated organic materials field. The Rasmussen group has previously demonstrated the ability to produce tunable, low band gap materials through the generation of new families of functionalized thieno[3,4-b]pyrazines (TPs). The scope of conventional TPs has been limited to either 2,3-dialkyl or diaryl analogues due to the standard synthetic approach of 3,4-diaminothiophene condensation with available stable α-diones. As a consequence, this limited the ability to effectively tune the electronic and optical properties of the TP unit. In an effort …
